Closing this as covered by the merged docs update in #554.

The new Sequence Feature Cookbook consolidates the common sequence/VarLen/DIN/DSIN input conventions, including VarLenSparseFeat shapes, padding and length_name, embedding sharing, DIN/BST history fields, DSIN session inputs, and Estimator/TFRecord vector inputs.
